We prove both Theorem 3.1 and 3.2 by induction on the dimensionality of the hypercubic lattice m.
The proof of Corollary 1 follows immediately from Theorem 3.2 and from the property of the Fourier transform according to which multiplying in the Fourier domain implements a convolution in the original domain.
